And I note also, that Revelation really doesn’t address Islam as a significant end times conversion opportunity. Jews yes. Muslims are background noise in Revelation—among the ones who see the miracles and the overwhelming evidence of Jesus reign on Earth and still refuse to believe.
That said, every Muslim who turns to the Lord will cause rejoicing in heaven and Earth and Evangelism to Islam should be and is a high priority of the Church.
The advent of the Lord, first in spirit (which this move with Donald Trump may herald) and then in person, could be well poised to crowd out the brunt of Islam. It’s driven and energized by the devil. Get the devil cowering in corners, and the steam goes out of Islam.
